Description

technical field [0001] The invention relates to the field of broadcasting and television, in particular to an audio and video editing device and editing method. Background technique [0002] In the field of broadcasting and television, audio and video editing mostly adopts linear editing methods. The linear editing method is based on the linear recording of the tape, and generally can only be recorded in the order of editing. Although the use of insert editing allows the replacement of the sound or image on the recorded tape, this replacement can only replace the old segment of the same length, and cannot change the length of the program. If the length of the program needs to be changed, the program after the segment needs to be re-recorded. As a result, TV programs often need to be adjusted many times from the sample to the final version, so it is very inconvenient to modify the program. [0003] In addition, the essence of the linear editing method is copying, which is ...
